never officially had free because of snow/cold weather when i was in school.
when it was too cold/icy we just decided ourself not to go to school and made a call to all our friends to be sure the entire class wont be there.
not because we were bad bad rebels, our school just had a bunch of total idiots @ lead.
i remember one year, the woule region was just a piece of ice. Not a single car on the streets and just a half dozen people. Impossible to walk over the streets. the few who had to go out were forced to move forward "down on all four"
Even in such days the school told us "YOU have to come to school" lol
